Question

I have a DataGridView that I’m binding to a DataTable.
The DataTable is a all numeric values.
There is a requirement that every n rows in the DataGridView has text in it, rather than the numeric values (to visually separate sections for the user).

I am happy to put this text data in the DataTable or in the DataGridView after binding, but I can’t see a way to put this text data in either as the column formats for both require numeric data – I get a ‘can’t put a string in a decimal’ error for both.

Any ideas how I change the format of a particular row or cell in either the DataTable or DataGridView?

You can provide a handler for the DataGridView’s CellFormatting event, such as:

public partial class Form1 : Form {     DataGridViewCellStyle _myStyle = new DataGridViewCellStyle();      public Form1()     {         InitializeComponent();          _myStyle.BackColor = Color.Pink;         // We could also provide a custom format string here          // with the _myStyle.Format property     }      private void dataGridView1_CellFormatting(object sender,          DataGridViewCellFormattingEventArgs e)     {         // Every five rows I want my custom format instead of the default         if (e.RowIndex % 5 == 0)         {             e.CellStyle = _myStyle;             e.FormattingApplied = true;         }     }      //... }
